Nuclear Power Plant Safety Systems

This video explains the main safety systems of Canadian nuclear power plants. The systems perform three fundamental safety functions: controlling the reactor, cooling the fuel and containing radiation. All of these systems are maintained and inspected regularly, and upgraded when necessary, to ensure plants meet or exceed strict safety standards established by the Canadian Nuclear Safety Commission (CNSC).

Way different reactor, and different fuel. Hilarious post & comments...

@Alexandru LMFAO!!!

[@solarissv777]

@Matt S Dyatlov wrote the instruction for the test, but there were no third-party body to reexamine this instruction. Don't forget Bryhanov, it was his decision to abort the standard reactor stopping sequence to obey the dispatcher request (this caused xenon poisoning), also Bryhanov and Fomin were the only people that had to check Dyatlov's instruction. USSR was in general overly complacent with nuclear energy. RBMK is neither safe nor stone age. It is incredibly advanced reactor (especially for it's time) that was extremely powerful however very hard to control (note computers of those day's, especially soviet ones were significantly inferior then your phone 10 years ago). It was easy to build, as it doesn't require high pressure hull, and USSR could't make those hulls in numbers that were needed. The main flaw of this reactor is the fact that water boils inside, so in certain modes it has positive reactivity. Many people knew about it's flaws by the time of 1986 there were several accidents with it with the most significant on the Leningrad NPP, in fact the "rode end effect" was known, and there was a standing instruction to adjust control rodes to be 0.5 m lower. But people were too complacent. Here is a great interview of ex Zaporizhia NPP director, who also took part in building Chernobyl NPP confinement about causes of the disaster kzbin.info/www/bejne/amPWpWOrp96ngqs (English subtitles included)

[@solarissv777]

@Matt S reactor would already be shut down by that night if not for Bryhanov, he should have declined dispatcher's request.

[@solarissv777]

@Matt S the reactor was already planned to be shut down for maitenance, one does not simply change reactor working cycle, it is dangerous for any reactor (except for some new designs, but none of them has been built yet), yet alone for RBMK. Man from interview I posted above had refused to prolong work of much safer WWER reactor in similar circumstances, he explained his decision to dispatcher afterwards. Bryhanow didn't even try arguing with a dispatcher.

People who come because of the HBO series: look for RBMK type of reactors, because this one works in different way and not so old than Chernobyl's one.

[@PointyTailofSatan]

Sadly, people see disasters like Chernobyl, and think all reactors are equally prone to similar fates. But the fact is that Chernobyl was an ancient Soviet era design that was terrible, because they wanted it as cheap as possible. So bad in fact, that it was practically a disaster waiting to happen. Modern designs, and in particular, the Candu design, have so many overlapping safety features, failure is almost impossible. Even concern over spent fuel is dumb. The fuel still have a huge amount of energy left. It's just cheaper right now to use new fuel instead of recycling the old. But some day the spent fuel will be like money in the bank, once it's cost efficient to recycle it.

[@zolikoff]

Chernobyl wasn't just an inherently faulty design, it was a deliberately manufactured accident as the operators deliberately placed the reactor into a critical condition, trying to perform a "safety" test. It may surprise you, but there's still about ten reactors identical to the Chernobyl design, still in operation, and have operated safely for decades. Even in Chernobyl, the still operational reactors were kept operating to provide electricity for a long time. The last of its reactors was shut down in 2001, 15 years after the accident.

You are also talking about BWRs on a page about safety systems for PWRs. On top of that, this model of PWR utilizes 2H to allow for better control and neutron moderation, as well as shielding. It also has far more safety systems, and aren't built in geographically extremely dangerous areas. Wouldn't surprise me if you think 2H fusion is just as dangerous.

[@moonasha]

These reactors are ancient by modern standards. New reactors are passively cooled when powered down. That is, they do NOT require electricity to cool the fuel. It's a huge step forward in safety. Many more safety features like this have been developed but have not been implemented yet due to lack of funding.

Our American type of Nuclear Power Plant is the Silo Plant. We use 4 cooling silos that direct water into heating systems that heat the water up into steam that powers the same turbines and generators that generate electricity. We use the same fuel and reactors to make the electricity. Just one fuel log can power up to and over 170 homes for just one year. However, our reactors use the hot water from the cooling towers as its power source, and they can to automatically shut down. Our reactors also use Uranium Fuel Rods to power the reactors themselves. The left over hot water goes back into the cooling towers to be cooled down again and then sent back to the water source that the water came from in the first place. So that's how our power plants work. Plz like and love this comment. It would be most appreciated if you did so.

Low cost energy production in a closed loop vacuum system: You have a water tank filled with degassed deionized water, the water then goes through black pipes held in glassed-in insulated boxes so sunlight is captured to heat the water "it can get hot enough to boil at sea level" the piping then goes to a spray nozzle where the hot water instantly vaporizes the steam then goes to a turbine that drives an electrical generator, after the turbine the steam and any water that condensed in it travel at a downward angle through a pipe with a condensation coil around it to a large vacuum chamber that has heat transfer fins inside this preheats water from a large reservoir tank that then feeds to the starting tank. The constant rapid condensation of the steam combined with a volume of the vacuum chamber being 3x or larger than the volume of steam produce at any given time maintains the vacuum level so the process continues.

Great examples of "fail to safe" engineering, where when something fails the system reverts to its safest state. Another simple example would be an emergency push button, where most people assume that you have to press the button for a signal to be sent, however, the reality is that the button must be not pressed for the signal, and pressing it actually opens the input and stops everything. The reason it's called fail to safe or "fail safe" is because if the button becomes damaged or prevents the circuit from closing, then nothing works. It failed and the system is safe.

[@strangejmaster]

What do you mean "Fukushima triple meltdown failsafe"?? The reactor got hit with a tsunami after the largest earthquake ever recorded in Japan. In this case I don't think any failsafe would help this

[@Ed-ty1kr]

@@strangejmaster The backup generators that were in a basement, needed to keep the pumps running so as to keep the reactor cool while it scrams and shuts down, then cools off. Elecricity from diesel generators is needed for that, and the spent fuel pools that stored decades of used fuel elements that also needs cooling. What I mean is they could have placed them above ground, and the backups to the backup generators were on trucks 5 miles inland, so that they survive the tsunami... except that the tsunami covered all the roads with debris and rubble, which they also failed to account for. Do you understand now how that works. You need generators to keep pumps running so the water circulates while the reactor cools, for the failsafe to work. That or the water inside the containment structure boils away, and the chemical reactions cause hydrogen to be generated, which then ignites in a huge explosion, which is what happened.. But if you didnt understand what a reactor SCRAM procedure entails, then Im not expecting you to understand why hydrogen is generated in exposed radioactive fuel elements, that are no longer submerged in a moderator which is the water inside the containment structure.

Well nuclear energy isn't all that amazing until we figure out how to do create a controlled fusion reaction. The best we have right now would be a molten salt reactor

[@Ucceah]

how do those work without chuit and 'erbs, or when the cooling system would be perforated by one major shaped charge?

[@AcvaristulLenes]

Seen quite a few videos about power plants of all kinds but nobody explains how is water refilled in the steam generator when it's under high pressure. A good source (link) of information would be welcome.

Can these safety measures stand up to Homer Simpson at the helm?

[@Blaze6108]

+dorpth I like to think that nuclear engineers use Homer Simpson as a metric of safety level. Homer Simpson-proof = anything-proof

[@puncheex2]

To the same extent that other power systems do so, yes, its possible. We've been using pressure boilers for 400 years; we know how they work, and yet every so often, one explodes. Is that acceptable? It will be, when the technology is equally mature, be possible to limit the damages just as much as they are limited for boilers today.

[@kysz1]

Yes, they do. But Homer Simpson would not be in control room. He would mistakenly go to the reactor room.

[@hzuiel]

If they are passive, then yes. I know you're joking, but still, they said multiple times in the program that some of these systems operate without power and without operator intervention.

It seems like there are barely any control rods compared to BWR reactors.

[@collinbarker]

@@thehammurabichode7994 British Columbia and Ontario are something like 70 and 40% hydroelectric to begin with. Rest of base power is nuclear, and wind is sitting around 10% in Ontario. We'll still need nat gas jet engine to to the minor corrections to the grid, but last coal plant is shutting down now in maritimes. Oil is still used in prairries, due to alberta

[@PAYPALMEAARONLYSTILA]

so heavy water is really alchol.... Thats why its so effecient and safe. anyways love you guys. good merger few years ago with the east. Its a treat to see your stuff over there running perfect as usual. Coal plants that dont need air... amazing.

[@PAYPALMEAARONLYSTILA]

That sub bit market is so huge though also. and the hyper and super critical coal industries provide so much other materials to capture and use. Its why no north american exports of naptha anymore. All the east sub bit coal plants. and they moved also on to that plasma low grade gas waste (nuc florene thing) and have it so small scale its everywhere i guess. Just little generators on buildings..... Kinda neat too. we always in usa though so large for power needs we missed the small generator market. memere and pepere would be proud of what you did with CANDU.

[@CarlosAM1]

alcohol is flammable, heavy water is not.

[@YamiPoyo]

So ive seen many diagrams of the adjuster rod system and they all seem to be missing a few rows of rods to stop the far left and right fuel from reacting

Thanks for Informatic Video!

[@IceSlushi]

Canada needs to be a global leader in Nuclear Power and prime exporter of fossil fuels.

[@Nikita__POPOV]

Great video! Thank you for making it. Do you have any docs about safety systems? It'd be so generous of you if you share this with me

[@Ed-ty1kr]

No safety system, Murphy's Law rendered those obsolete... but I'm sure they have a few documents on how to perform a seamless coverup.

[@zerotonine807]

It is the cleanest and most effective source for us.....but then unfortunately the disadvantages keep coming.

[@ArtyomGalstyan]

like what? Last one was 8 years ago in Fukushima... Only because of earthquake.

[@dont_care1591]

accidents are very rare but the consequences can last hundreds of years

[@hzuiel]

@@dont_care1591 No they don't, chernobyl is approaching livability again, and it was a rather unique disaster. Probably another 20 years and they could start cleanup and letting people re-settle the area. Scientists have been studying the animals there for some time, they not only survive but thrive, not nearly as bad as was once thought the effect would be on living creatures. In 100 years, the hottest fission products are either long gone or greatly reduced. Isotopes with half lives in the days, months, or single digit years would be completely gone. Isotopes with half lives around 30 years would be about 10% of their original radioactivity. Even without any effort to do cleanup, like removing top soil and plants to sequester them, not only would the "consequences" not last multiple hundreds of years, but you'd be pretty hard pressed to even prove a nuclear accident happened in a particular location after 200-300 years. You'd have to take a lot of sample and test with very sensitive equipment to look specifically for manmade isotopes with medium to long half lives(which also means cooler, less radioactive).

Such an uneducated point of view. Modern nuclear plants are incredibly safe. Any "catastrophe" are anomalies. Like how one or two doctors are serial killers. You don't boycott doctors.

[@beluwuga2229]

• 72 years ago wtf it’s a joke

[@genekelly8467]

CANDU reactors have a mixed record-very expensive to build. Really old design with some good features (don't need enriched fuel), but very complex.

[@kishorekurtakoti1225]

Nice introductory video. A brief mention of Basic ASME design, construction codes and Safety regulations would add to the usefulness of the video .
